In re Nectar Mattress Fiberglass Litigation Settlement and Public Filings
Federal Court Docket
Did Nectar Switch Away from Fiberglass?
Timeline and law label review: Nectar's transition away from glass fiber fire socks toward rayon and chemical flame barriers following class-action litigation.
Yes: Transitioned Away from Glass Fiber
Direct answer summary
Yes. Following extensive consumer class-action litigation regarding fiberglass contamination from unzipped covers, Resident Home (parent company of Nectar) reformulated its flame barriers. Nectar law labels published after late 2022 indicate a transition away from woven continuous filament fiberglass. Current production utilizes flame-retardant treated rayon, modacrylic, or hydrated silica barrier socks, though covers still feature warnings against unzipping.
Key points
Nectar phased out continuous filament fiberglass following nationwide class-action lawsuits.
Beds produced after late 2022 utilize flame-retardant rayon, modacrylic, or silica socks.
Law labels on older pre-2022 Nectar mattresses still state '71% Glass Fiber'.

Checklist
Comparative Spec Verification Checklist
Step-by-step inspection to detect mid-production substitutions and compare component specs.
- 01
Check Manufacture Date on Law Tag
Inspect the date of manufacture on the law tag: pre-2022 beds contain fiberglass.
Watch for: NEVER UNZIP OR WASH THE COVER OF ANY NECTAR MATTRESS REGARDLESS OF AGE.
- 02
Use Waterproof Mattress Protector
Encase the entire mattress in a zippered waterproof encasement to seal the cover.
Watch for: Washing the outer cover destroys the flame barrier and voids warranty.
- 03
Conduct Blacklight Test if Concerned
Shine a 365nm UV blacklight across seams in a dark room; glass shards will glow bright white.
Watch for: If glass fibers leak, do not use a standard vacuum; hire a HEPA remediation crew.
